2 Claims.

This invention relates to new and useful improvements in valve removersfor internal combustion engines.

The principal object of the present invention is to provide a devicewhereby all the valve springs of an engine can be held simultaneously topermit removal of the holding keys in quick succession.

Another important object of the invention is to provide a device of thecharacter stated which can be readily applied and removed with respectto an internal combustion engine.

Other objects and advantages of the invention will become apparent tothe reader of the following description.

In the drawings Figure 1 represents a plan view showing the valveremover applied to an engine head.

Figure 2 is a side elevational view of the apparatus in use on an enginehead.

Figure 3 is a side elevational view looking at the opposite side fromthat shown in Figure 2, showing the apparatus applied to an engine 1head.

Figure 4 is a fragmentary detailed sectional view taken substantially onthe line 4-4 of Figure 1.

Figure 5 is a perspective view of one of the spring holding sleeves.

Figure 6 is a side elevational view showing the engine head invertedpreparatory to removing the valves.

Figure 7 is an end elevational view of the structure as represented inFigure 6.

Figure 8 is a side elevational view of one of the stand bolts.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that numeral 5 denotes an engine head having valve seats 6against which valves 1 are operated. These valves 1 have stems 8 onwhich are springs 9, these springs 9 being held in place by cups I0abutting pins II extending through openings in the free end portions ofthe stems 8.

In carrying out the present invention, an elongated bar I2 is providedat certain spaced intervals with slots I3 through which the free endportions of the stems 8 with their key pins I I can protrude, as issuggested in Figure 2.

In addition the present invention includes a pair of L-shaped arms I4,I4, the foot portions a of which have threaded openings therein forreceiving the threads of clamp screws I5, each of which has a crankhandle I6 at one end and an engine head engageable member I! at itsopposite end.

The remaining ends of the arms I4 have openings therein to permit theseends of the arms I4 to be slipped over the opposite ends of the bar l2and secured in place by set screws I8.

Arranged on the bar I2 are spring holding sleeves I9 equivalent innumber to the springs 9 to the particular engine head being handled.Each of these sleeves I9 has a pair of diametrically opposite legs 20 atone end thereof and each of these legs has an inturned lug 2I whichoverlaps the bar l2. These legs 20 and lugs 2| permit the sleeves I9to-be slid to any desired adjusted positions on the bar I2. In otherwords, these sleeves I9 are adjusted on the bar I2 and the bar broughttoward the head 5 so that the sleeves I9 are disposed over substantialportions of the springs 9.

The arms I 4 are then applied to the bar I2 and the clamp screws I5operated inwardly so as to draw the bar I2 toward the top side of theengine head 5. It is, of course, understood that the engine head 5 isset on one side as suggested in the top plan view, Figure 1, so that theclamp screws [5 can be conveniently operated and so that when the bar I2has been drawn in close enough to the top side of the engine head 5, thespring retaining pins I I can be easily removed as they will then beprotruding beyond the outermost side of the bar I2.

When the pins I I have been removed and subsequently the springs 9,stand bolts 25 can be applied. Each of these bolts 25 has a threadedportion 1) and on each threaded portion b are nuts 26, 21. The threadedportions 1) of these bolts 25 can be disposed through the corneropenings 28 of the engine head 5 and the bolts 26 driven against theopposite sides of the engine head. Thus, supporting legs are providedfor the head 5 so that the head 5 can be supported in inverted positionas shown in Figure 6, thus permitting easy removal of the valve elementsand convenient positioning of the head for various operations thereon.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the claimed as new is:

1. A spring remover for engine heads comprising an elongated bar formedwith openings thereinvention, what is in for receiving the springretaining pin ends of valve stems, a pair of arms each having an openingin one end thereof for receiving a corresponding end of the bar, andclamp means on the remaining ends of the arms for exerting force againstthe corresponding side of an engine head, and a plurality of sleeves onthe bar for embracing valve springs, each of the sleeves being providedwith means for slidably connecting the same to the bar.

2. A spring remover for engine heads comprising an elongated bar formedwith openings therein for receiving the spring retaining pin ends ofvalve stems, a pair of arms each having an opening in one end thereoffor receiving a corresponding end of the bar, and clamp means on theremaining ends of the arms for exerting force against the correspondingside of an engine head, and a plurality of valve spring embracingsleeves, each of said sleeves being provided with a pair of legs at oneend and lugs on the legs for overlapping the bar to slidably connect thecorresponding sleeve to the bar.
